MARYLAND FLOW REPORT
Last Updated: December 24, 2025
Maryland's river conditions present a mixed bag for water enthusiasts this season, with most streamflow measurements well below normal across the state. Notably, the Susquehanna River at Conowingo, a major watercourse in Maryland, is experiencing streamflow that is 65.15% below normal at 13,100 cubic feet per second (cfs), with a current gage height of 10.86 feet, which could impact activities near Darlington. Deer Creek near Darlington is also running low at 103 cfs, 72.68% below normal, likely affecting local ecosystems and potentially altering fishing conditions. River levels in the Potomac watershed are similarly reduced, with the Potomac River near Washington, D.C. at a low 2500 cfs, 82.94% under the seasonal average, which could concern urban planning and recreational activities. These low flows may indicate an ongoing flow drought, posing challenges for water-based recreation such as kayaking, especially on typically popular whitewater trails.
Conversely, a significant increase in streamflow was observed in the North Branch Potomac River at Steyer, which surged by 73.17% in the past 24 hours to 213 cfs, although still 4% above normal levels, indicating a localized increase that warrants monitoring for potential flooding. The Youghiogheny River at Friendsville, a favorite among whitewater enthusiasts, also showed a notable rise to 791 cfs, an 80.18% increase, but remained 5.16% below the normal level. This could create excellent conditions for advanced rafters and kayakers seeking a challenge, but it necessitates caution due to the rapid change. Such fluctuations underline the importance of staying informed on current river conditions for safety and optimal enjoyment of Maryland's diverse waterways.
Maryland's flow conditions are heavily influenced by its location along the Atlantic coast and the Chesapeake Bay, as well as its varied topography. The state experiences a humid subtropical climate, with hot and humid summers and mild winters. Major surface flows include the Potomac and Patuxent Rivers, which feed into the Chesapeake Bay. Reservoirs and dams such as the Conowingo Dam and Loch Raven Reservoir also contribute to the state's hydrology. The state's watershed includes the Chesapeake Bay watershed, which covers 64,000 square miles and includes six states and the District of Columbia. Snowpack in the Appalachian Mountains can also impact flow conditions in the state. Overall, Maryland's flow conditions are complex and influenced by a variety of factors.
